Given numbers are 242,945,806,390,939
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,945,806,390,939 is 28846727910.
Find LCM of 242,945,806,390,939 with Prime Factorization
| 2 | 242, 945, 806, 390, 939 |
| 3 | 121, 945, 403, 195, 939 |
| 5 | 121, 315, 403, 65, 313 |
| 13 | 121, 63, 403, 13, 313 |
| 121, 63, 31, 1, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 121 x 63 x 31 x 1 x 313 = 28846727910
Therefore, the lowest common multiple of 242,945,806,390,939 is 28846727910.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
242 x 945 x 806 x 390 x 939 = 67501343309400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
242 : 1, 2, 11, 22, 121, 242
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
806 : 1, 2, 13, 26, 31, 62, 403, 806
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
939 : 1, 3, 313, 939
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,945,806,390,939, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
945:3x 3x 3x 5x 7
806:2x 13x 31
390:2x 3x 5x 13
939:3x 313
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5x 13 = 2340
Therefore, the value for common factors is 2340.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 67501343309400/(1x2340)
LCM = 67501343309400/2340
LCM = 28846727910
Thus, we can understand that the LCM of 242,945,806,390,939 is 28846727910.
